<BS> doesn't seem to work.

[romainl]

I'm using an up to date MacVim 7.3 both in GUI and CLI mode on Mac OS X 10.6.8 and a slightly older Vim 7.3 also in GUI and CLI mode on Ubuntu 10.10.

When I type (, smartinput correctly inserts the matching ) but I'm not able to "undo" the () pair by hitting <BS>. Only the first ( is deleted instead of both parenthesis. Of course, it's the same for all the other pairs ''""{}[].

Please let me know if you need more informations.

Thank you.

Please tell me the result of :set backspace? in your Vim. I suspect it depends on your 'backspace' value, because several rules require that 'backspace' is set to "indent,eol,start" or 2.

• If the result is neither backspace=indent,eol,start nor backspace=2, please :set backspace=indent,eol,start.
• Otherwise, it might be a bug in vim-smartinput. Please tell me the result of :version. I'll investigate it later.

Only the first ( is deleted instead of both parenthesis.

Ah, I overlooked this sentence. It might be caused by key mappings which are defined in your vimrc or other plugins. Please let me know the results of :imap <BS> and :imap <Del> in your Vim.

[romainl]

Thanks for your reply.

I have set backspace=indent,eol,start in my ~/.vimrc. :set backspace? returns the same line so it's not overwritten anywhere.

1. :verbose imap <BS>

   i    <BS>    & <SNR>28__trigger_or_fallback("\<BS>", "\<BS>")
       Last set from ~/.vim/bundle/smartinput/autoload/smartinput.vim
   

2. :verbose imap <Del>

   No mapping found
   

Ho, I forgot to add that I use 0.0.5.

Thanks again.

[kana]

Thank you for the information. I'll investigate it later.

By the way, is the problem still reproducible if Vim is invoked by the following command?

vim -u NONE -i NONE -N -c "set backspace=2 runtimepath^=$HOME/.vim/bundle/smartinput | runtime! plugin/smartinput.vim"

[romainl]

No. Backspacing works as advertised with this command. It means that the problem is elsewhere.

My vimfiles are here.

[amjith]

I'm seeing the same problem as @romainl.

backspace=indent,eol,start

[amjith]

I just cross-referenced my plugins with @romainl's plugins and found the problem plugin.

If I remove the autocomplpop plugin, the BS works as advertised. I wonder what's the conflict between the two plugins.

[jordwalke]

ACP.vim remaps backspace internally, but IIRC it does not restore the mapping. ACP.vim is also one of the most popular plugins so it would be nice to have smart-input work well with it (even if that means that we must fix ACP.vim) NeocomplCache (ACP.vim alternative) does not ruin the <BS> mappings in the same way that ACP.vim however, it's nowhere near as fast as ACP.vim so I'd like to get these two plugins working correctly together.
